To develop a business continuity plan you must have a thorough understanding of your business, including its critical functions, their priority and the effect of them being disrupted.

You should consider the importance of each function on the survival of your business (percentage of income or work load, how critical the function is to other functions, etc) and how quickly each must be re-established. For each of the time spans, identify what the effect of the loss of the function would be. For example, disruption to the goods-in function could have the following effect:
